System and method for notifying users of an event using alerts

ABSTRACT

An alert engine module receives an alert for an event in a generic communications format and delivers an alert for the event to a target address in a communications format that is preferred by a user based on the alert content. The generic format can be an e-mail message, such as a Simple Mail Transfer Protocol (SMTP) message. The alert engine can be operative to transform the alert based on a header and/or format of a target address.

FIELD OF THE INVENTION

The present invention relates to communications and electronicmessaging, and more particularly, the present invention relates to asystem and method for notifying a user of an event using an alert.

BACKGROUND OF THE INVENTION

Users of electronic mail and messaging systems often want to be notifiedof an event, which could be a notification that an e-mail message hasbeen received in a mailbox or be a notification regarding a telephonemessage, stock quote notification, or other notification regarding areceived message. Sometimes a user may have a preferred medium orcommunications format for receiving the alert, including an e-mail ShortMessaging Service (SMS) message, a Wireless Application Protocol (WAP)message, or other type of message to be delivered in a communicationsformat that is preferred by the user at the destination or targetaddress.

There have been a number of prior art proposals for solving theseproblems and providing alerts for events. For example, sometimes analert is delivered to a distribution engine in an output communicationsformat desired by the user. This distribution engine, however, performsno transformation of an alert into a communications format desired by auser or destination address. Thus, any alert must be input in thedesired format. In yet another proposal, the input format to an alertsystem can originate from a variety of sources, and can be in the formHypertext Transfer Protocol (HTTP), local files, File Transfer Protocol(FTP), Structured Query Language (SQL), and other multiple formats. Inthis prior art proposal, the alert system appears to have access to auser's personal information and settings, but there is nottransformation into a desired communications format

U.S. published patent application no. 2002/0087643 provides anotification system and generates alerts. Messages are left for a user,for example, a voice mail, an e-mail, or a CRM event. Different foldersare maintained by messaging services. The notification system detectsany additions to a user's folders and when a new message arrives, thenotification system sends an alert to a Wireless Access Protocol (WAP)enabled device, e.g., cell phone, configured for the user. The alert caninclude a number of messages of each type received for the user and anindication of a most recently received message. The notification systemcould monitor an information source for new information that may be ofinterest to the user and provide these as an alert notification whencertain conditions are met.

In U.S. published patent application no. 2002/0129354, a series oftemplates allows a user to define events and information alerts to betriggered by the events. A knowledge switch uses event definitions andcontacts and schedules information to detect events and distributesalerts to intended recipients when an event occurs.

Many of these prior art proposals identified above do not provide analert to a user in a communications medium or protocol preferred by auser, at the target address desired by the user, whether e-mail ormobile phone. For example, different users could desire an alert in theform of an e-mail, SMS, WAP or other communications protocol. Also, itwould be desirable if any alert engine that delivers an alert has accessto a user profile in order to deliver this alert in a communicationsformat preferred by the user.

SUMMARY OF THE INVENTION

The present invention advantageously allows a user to be notified of anevent by means of an alert. The alert content is first received in analert engine module in a generic communications format, for example, ane-mail over the Simple Mail Transfer Protocol (SMTP). The alert enginemodule transforms this alert and delivers the alert to an intended userat a target address in a communications format that is preferred by auser typically based on alert content.

In yet another aspect of the present invention, the alert engine isoperative to transform the alert based on a header and/or format of atarget address. The alert engine module could be operative to deliverthe alert to an appropriate gateway in the preferred communicationsformat. This target address could be a mobile device and the alertengine module could be operative for transforming the alert that isreceived by the alert engine module into a format based on the type ofmobile device.

The communications format could be a short messaging service message,which could be the default type of communications format or protocol.The communications format could also be a Wireless Application Protocol(WAP) message, an e-mail message, an over-the-air (OTA) message or apocket PC (PPC) message.

In yet another aspect of the present invention, an input queue willqueue a plurality of events, typically all based on the genericcommunications format. The alert engine pulls alerts from the inputqueue and delivers each alert for a respective event to a target addressin the preferred communications format. The target address, of course,could be an appropriate gateway. An output queue can queue alerts fordelivery.

A method and computer readable medium are also disclosed and set forth.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

The present invention will now be described more fully hereinafter withreference to the accompanying drawings, in which preferred embodimentsof the invention are shown. This invention may, however, be embodied inmany different forms and should not be construed as limited to theembodiments set forth herein. Rather, these embodiments are provided sothat this disclosure will be thorough and complete, and will fullyconvey the scope of the invention to those skilled in the art. Likenumbers refer to like elements throughout, and prime notation is used toindicate similar elements in alternative embodiments.

The present invention advantageously permits a user to be notified of anevent by having an alert engine module receive a message alert for anevent in a generic communications format, such as over SMTP, andtransforming the alert into a communications format that is preferred bya user at a target address such as based on alert content. The alert isdelivered to the target address, such as through a gateway for thatdesired communications format. The present invention is advantageousover other prior art proposals that deliver alerts to a distributionengine in an output format without transformation. These prior artproposals typically mandate that the input format must be the formatdesired by a user. The present invention is also advantageous over otherprior art proposals where an input format to a system could be from avariety of sources such as Hypertext Transfer Protocol (HTTP), localfiles, File Transfer Protocol (FTP), and Structured Query Language (SQL)in multiple formats. In the present invention, the alert system hasaccess to any personal information of a user based on the output formatfor the alert.

FIG. 1 illustrates at 10 a block diagram of one example of a system thatcould be used for the present invention. A number of sources 12 causeevents and inputs as messages into a server 14. These sources 12 areillustrated as examples only and include a corporate e-mail 12 a,personal e-mail 12 b, stock market network news 12 c, phone message 12d, and e-mail client provisioning document 12 e for over-the-air (OTA)messages. These sources 12 can deliver an e-mail message as an event ordeliver other messages as events to a mail or other server 14. A SMTPmessage 20 is forwarded as an alert from the server 14. The server 14,of course, could be any number of servers for the different sources.

The alert engine is shown generally at 30 and includes an input queue32, an alert engine module 34, and an output queue 36. Typically, thealert is forwarded as a message to the alert engine 30 over SMTP. Thealert engine 30 queues the alerts in the input queue 32. The alertengine module 34 pulls each alert from the input queue 32 and transformsthe alert into the communications format desired by a user at a targetaddress 40, for example, a user's mobile device, such as a hand-heldBlackberry unit. The communications format could be, but not limited to,Short Message Service (SMS), Wireless Application Protocol (WAP),e-mail, pocket PC (PPC), which is typically over-the-air (OTA). Thedesired format or protocol can be chosen based on certain headers and/orthe format at a target address. Typically, the alert engine module 32 isoperative with the output queue 34, such that successive alerts can beoutput for later delivery to a target address. As illustrated, thetarget address could include a gateway 50 as a server for the type ofcommunications protocol desired. The gateway could be a single ormultiple gateway for the illustrated SMS 50 a, WAP 50 b, E-mail 50 c,and PPC, OTA 50 d, as non-limiting examples. The original message orevent as sent over SMTP to the alert engine 30 could have headerinformation with details required for transforming the message andaccessing the user device. POP proxy servers and other servers could beused. The output could vary and include corporate intranets or otherintranets and internets.

In one aspect of the invention, the SMS message is the default messagethat the alert engine module 34 transforms. It should be understood thatSMS is a wireless service and encompasses different embodiments fortransmitting alphanumeric messages. SMS can be used in many differentpersonal communications service (PCS) networks, including TDMA, CDMA andGSM systems. It can include a point-to-point system using a ShortenedMessage Service Center (SMSC) to store-and-forward short messages.Alerts can be received any time whether a voice or data call is inexistence. It includes out-of-band packet delivery and low bandwidthmessage transfer.

The SMS network architecture could include a short messaging entity(SME) and a short message service center (SMSC) to relay andstore-and-forward a short message. The SMS system could include aSMS-gateway/interworking mobile switching center (EMS-SMSC), homelocation register (HLR), mobile switching center (MSC), visitor locationregister (VLR), base station system (BSS), and of course, the mobilestation (MS). It can use a Mobile Application Part (MAP) layer and usean SS7 Transaction Capable Application Part (TCAP). MAP operations couldinclude a routing information request and point-to-point short messagedelivery and a short message waiting indication. The SMS system couldalso include a service center alert. Different services could include amobile-originated short message (MO-SM) or a mobile-terminated shortmessage (MT-SM). Many different characters can be stored.

A Wireless Application Program (WAP) could define an applicationenvironment and communication protocol for wireless devices tocommunicate across the internet. Applications could be written in awireless mark-up language (WML), a subset of the extensive mark-uplanguage (XML) The architecture could use a WAP datagram protocol (WDP)as a transport layer. A Wireless Transport Layer Security (WTLS) can addsecurity. The WAP session protocol (WSP) layer could be a session layerand the HTTP interface retrieves WAP content.

As to the PPC (pocket PC), OTA (over-the-air) message communications foralerts, the system can be used in conjunction with a short messagingservice and allow transfer of small text files. OTA messages can beencrypted. There is an OMA (open mobile alliance) document on OTAprovisioning of WAP clients as mobile devices. This specification isused initially to provision unconfigured WAP clients. In the presentsystem, it is possible to support this over the air provisioning of WAPclients. For example, a user may provision access to an ISP/corporatee-mail mailbox in the present system. If the mobile device (phone orPDA) has a POP or IMAP client, then it is possible for the user toaccess their ISB e-mail using the system POP or IMAP proxy respectively.In order to accomplish this, the user would have to type in the user ID,password, POP server name, POP server port and whether to keep a copy onthe server or not and other parameters in the POP client on their phoneor PDA. This task of typing in parameters used in the phone keyboardwould be very frustrating to the user.

The present invention would alleviate this problem by creating an OTAprovisioning document containing a user's user ID, password, the systemPOP (or IMAP) proxy server's name, port and other default parameters.This could be sent in an e-mail to the alert engine. The alert enginewould transform this e-mail to suit the target device and deliver it tothe gateway or server. When the gateway delivers this message to thetarget device, it would configure the user's POP client with theseparameters and the target device becomes operable. The user can nowaccess their e-mail without having to know and type in any of theparameters required to use the system POP server.

This message can be created and sent to the alert engine when the userprovisions a new account or modifies their settings or deletes aprovisioned mailbox. In the instance when the user modifies theirsettings, the OTA-provisional document modifies the settings on thedevice. In the instance when the user deletes a provisioned mailbox, theOTA-provisional document deletes the settings from the POP client on thedevice. Although the mechanism of provisioning a target device's e-mail(POP/IMAP) client over-the-air is targeted at PPC users, it is possibleto extend this to various mobile phones and devices that support the OMAOTA/provisional specification.

It should be understood that the software and programming used for thepresent invention can vary, and different applications can be used toaccomplish the purpose and functions of the present invention. Manytypes of web service technology can be used, including differentapplication services used by those skilled in the art. Web servicescould include a combination of programming and data, which are availablefrom a web server for web users, or the use of other web-connectedprograms as provided by an application service provider. Web servicescould use an extensible mark-up language (XML) as a standard forformatting data to be communicated.

Different communication arrangements could be used, includingpeer-to-peer, use of a central server, or other architecture andcommunication systems, including middleware. Data formats could bestandardized and data exchanged using an extensive mark-up language(XML), which is the foundation for the web services description language(WSDL). Different web servers could also be used, including the opensource Apache or Microsoft's Internet Information Server (IIS). Otherweb services could include Novell's web server for users of its netwareoperating system or the IBM family of Lotus Domino service, for example,for IBM's OS/390 and AS/400 customers.

Any web server could download requests for File Transfer Protocol (FTP)files. Different servers could include a Messaging ApplicationProgramming Interface (MAPI) and provide an Application ProgrammingInterface (API). Configuration data objects and format data objectscould be generated using an extensible mark-up language (XML) forsubmission to various XML-compliant web services. Any server and webservice could be a Simple Object Access Protocol (SOAP) compliantserviced SOAP would allow one program running in one kind of operatingsystem to communicate with a program in the same or another type ofoperating system by using HTTP and XML for information exchange.

ActiveX controls could be used as Component Object Models (COM) andprovide a framework for building software components that communicatewith each other. ActiveX controls could be automatically downloaded andexecuted by a web browser. Distributed object applications could bebuilt in active web pages and ActiveX controls could be downloaded todifferent browsers and client. ActiveX controls could be held in a webbrowser as a container and distributed over an internet or corporateintranet. ActiveX controls could also manage and update web content andclient systems and work closely with a user interface of a targetedoperating system JAVA objects or similar component objects could be usedinstead of ActiveX controls. An object model control could also be anytype of Dynamic Link Library (DLL) module that runs in a container.

FIG. 2 illustrates a high level block diagram of an example of themethod of the present invention of notifying a user of an event. Anevent is triggered to the server 14 (block 100). An alert for the eventis received at the alert engine over SMTP (block 102). It is storedtemporarily in the input queue. The alert engine module draws the alertfrom the input queue (block 104).

The alert is transformed into a communications format that is preferredat the target address (block 106). The alert is delivered from the alertengine module through the output to a gateway server for a preferredcommunications format (block 108). From the gateway, the alert can bedelivered to a user in a preferred communications format (block 110).

The present invention advantageously permits a user to be notified of anevent by means of an alert, for example, based on the alert content,which is first received in an alert engine module in a generic format,for example, an e-mail that comports with the Simple Mail TransferProtocol (SMTP). The alert engine module transforms the alert anddelivers the alert to the intended user at a target address in acommunications format that is preferred by the user based on alertcontent. The generic format could be an e-mail message that comportswith the Simple Mail Transfer Protocol (SMTP)

An exemplary hand-held mobile wireless communications device 1000 thatcan be used in the present invention is further described in the examplebelow with reference to FIG. 3. The device 1000 includes a housing 1200,a keyboard 1400 and an output device 1600. The output device shown is adisplay 1600, which is preferably a full graphic LCD. Other types ofoutput devices may alternatively be utilized. A processing device 1800is contained within the housing 1200 and is coupled between the keyboard1400 and the display 1600. The processing device 1800 controls theoperation of the display 1600, as well as the overall operation of themobile device 1000, in response to actuation of keys on the keyboard1400 by the user.

The housing 1200 may be elongated vertically, or may take on other sizesand shapes (including clamshell housing structures). The keyboard mayinclude a mode selection key, or other hardware or software forswitching between text entry and telephony entry.

In addition to the processing device 1800, other parts of the mobiledevice 1000 are shown schematically in FIG. 3. These include acommunications subsystem 1001; a short-range communications subsystem1020; the keyboard 1400 and the display 1600, along with otherinput/output devices 1060, 1080, 1100 and 1120; as well as memorydevices 1160, 1180 and various other device subsystems 1201. The mobiledevice 1000 is preferably a two-way RF communications device havingvoice and data communications capabilities. In addition, the mobiledevice 1000 preferably has the capability to communicate with othercomputer systems via the Internet.

Operating system software executed by the processing device 1800 ispreferably stored in a persistent store, such as the flash memory 1160,but may be stored in other types of memory devices, such as a read onlymemory (ROM) or similar storage element. In addition, system software,specific device applications, or parts thereof, may be temporarilyloaded into a volatile store, such as the random access memory (RAM)1180. Communications signals received by the mobile device may also bestored in the RAM 1180.

The processing device 1800, in addition to its operating systemfunctions, enables execution of software applications 1300A-1300N on thedevice 1000. A predetermined set of applications that control basicdevice operations, such as data and voice communications 1300A and1300B, may be installed on the device 1000 during manufacture. Inaddition, a personal information manager (PIM) application may beinstalled during manufacture. The PIM is preferably capable oforganizing and managing data items, such as e-mail, calendar events,voice mails, appointments, and task items. The PIM application is alsopreferably capable of sending and receiving data items via a wirelessnetwork 1401. Preferably, the PIM data items are seamlessly integrated,synchronized and updated via the wireless network 1401 with the deviceuser's corresponding data items stored or associated with a hostcomputer system. Communication functions, including data and voicecommunications, are performed through the communications subsystem 1001,and possibly through the short-range communications subsystem Thecommunications subsystem 1001 includes a receiver 1500, a transmitter1520, and one or more antennas 1540 and 1560 In addition, thecommunications subsystem 1001 also includes a processing module, such asa digital signal processor (DSP) 1560, and local oscillators (LOs) 1601.The specific design and implementation of the communications subsystem1001 is dependent upon the communications network in which the mobiledevice 1000 is intended to operate. For example, a mobile device 1000may include a communications subsystem 1001 designed to operate with theMobitex™, Data TACT™ or General Packet Radio Service (GPRS) mobile datacommunications networks, and also designed to operate with any of avariety of voice communications networks, such as AMPS, TDMA, CDMA, PCS,GSM, etc. Other types of data and voice networks, both separate andintegrated, may also be utilized with the mobile device 1000.

Network access requirements vary depending upon the type ofcommunication system For example, in the Mobitex and DataTAC networks,mobile devices are registered on the network using a unique personalidentification number or PIN associated with each device. In GPRSnetworks, however, network access is associated with a subscriber oruser of a device. A GPRS device therefore requires a subscriber identitymodule, commonly referred to as a SIM card, in order to operate on aGPRS network.

When required network registration or activation procedures have beencompleted, the mobile device 1000 may send and receive communicationssignals over the communication network 1401. Signals received from thecommunications network 1401 by the antenna 1540 are routed to thereceiver 1500, which provides for signal amplification, frequency downconversion, filtering, channel selection, etc., and may also provideanalog to digital conversion. Analog-to-digital conversion of thereceived signal allows the DSP 1580 to perform more complexcommunications functions, such as demodulation and decoding. In asimilar manner, signals to be transmitted to the network 1401 areprocessed (e.g. modulated and encoded) by the DSP 1580 and are thenprovided to the transmitter 1520 for digital to analog conversion,frequency up conversion, filtering, amplification and transmission tothe communication network 1401 (or networks) via the antenna 1560.

In addition to processing communications signals, the DSP 1580 providesfor control of the receiver 1500 and the transmitter 1520. For example,gains applied to communications signals in the receiver 1500 andtransmitter 1520 may be adaptively controlled through automatic gaincontrol algorithms implemented in the DSP 1580.

In a data communications mode, a received signal, such as a text messageor web page download, is processed by the communications subsystem 1001and is input to the processing device 1800. The received signal is thenfurther processed by the processing device 1800 for an output to thedisplay 1600, or alternatively to some other auxiliary I/O device 1060 Adevice user may also compose data items, such as e-mail messages, usingthe keyboard 1400 and/or some other auxiliary I/O device 1060, such as atouchpad, a rocker switch, a thumb-wheel, or some other type of inputdevice. The composed data items may then be transmitted over thecommunications network 1401 via the communications subsystem 1001.

In a voice communications mode, overall operation of the device issubstantially similar to the data communications mode, except thatreceived signals are output to a speaker 1100, and signals fortransmission are generated by a microphone 1120. Alternative voice oraudio I/O subsystems, such as a voice message recording subsystem, mayalso be implemented on the device 1000. In addition, the display 1600may also be utilized in voice communications mode, for example todisplay the identity of a calling party, the duration of a voice call,or other voice call related information.

The short-range communications subsystem enables communication betweenthe mobile device 1000 and other proximate systems or devices, whichneed not necessarily be similar devices For example, the short-rangecommunications subsystem may include an infrared device and associatedcircuits and components, or a Bluetooth™ communications module toprovide for communication with similarly-enabled systems and devices.

Many modifications and other embodiments of the invention will come tothe mind of one skilled in the art having the benefit of the teachingspresented in the foregoing descriptions and the associated drawings.Therefore, it is understood that the invention is not to be limited tothe specific embodiments disclosed, and that modifications andembodiments are intended to be included within the scope of the appendedclaims.
